In order to accurately predict general aviation aircraft path, this paper puts forward the basic flight model prediction method based on data fusion. The 4D trajectory track is decomposed into horizontal and vertical section. The horizontal trajectory can accurately show the plane turning of the flight details. The vertical section can accurately express the change of aircraft flight altitude and...
A normalized function was proposed as the framework to study the heterogeneity of urban radar targets. The function consisted of three types of scales, the physical size of a target, heterogeneity in dielectric constant, and target geometry. The azimuth direction or azimuth scale, one component of the target geometry was exampled to investigate the influence of azimuth orientations of buildings on...
The application of distance differential capacitance sensors to measure micro vibrations is now widely witnessed in the field of earthquake engineering. However, the structure of detection circuits is correspondingly complex for the vibration signal is small. This design improved the situation by updating the switch device structure in switching phase-sensitive detection circuit. It is demonstrated...
The nonlinear loads exist widely in practical engineering applications. Due to the nonlinear characteristic of the loads, the nonlinear loads firstly need to be linearized to a resistor with constant value using the traditional stability analysis method based on the Routh-Hurwitz stability criterion and the method based on the stroboscopic map. In this paper, a novel stability analysis method is proposed...
Online word-of-mouth activity is a very typical index of the lifecycle evolution model of a product, and understanding product lifecycle can help corresponding decision makers with their formulation of marketing strategies. In this paper, the data sets for the online comments on various types of products are studied; based on management theory and economics theory, and by applying such methods as...
There are two key issues in applying simulated annealing method to solve the problem of ensemble clustering. One is improving the solution quality as much as possible, the other is accelerating the annealing process, thus obtain the solution rapidly. Aiming at solving the two questions, a rapid simulated annealing model for ensemble clustering, called BV-RSA, is presented. In BV-RSA, the partial consensus...
In this paper, a novel classification paradigm, termed Spectral-Spatial One Dimensional Manifold Embedding (SS1DME), is proposed for classification of hyperspectral imagery (HSI). The proposed paradigm integrates the spectral affinity and spatial information into a uniform metric framework. In SS1DME, a spectral-spatial affinity metric is utilized to learn the similarity of HSI pixels. Moreover, a...
It is desirable for an uniform power distribution in the chip during the dynamic burn-in, in which stimuli are inputted into the circuit under test. This paper uses the genetic algorithm to get an optimized input order of burn-in patterns for IP cores to approximate the uniformity of the power distribution in the SoC under the constraints of peak power and TAM width. The experimental results shows...
Scheduling problems in manufacturing systems and industrial engineering are very complex. If the scale of a problem exceeds a certain threshold, the problem is difficult to solve by traditional or formal optimization approaches. In this paper, scheduling problem is modeled with interval indexed formulation. In the model, intervals formation are very important to the efficiency of the algorithm. We...
No-wait job shop scheduling problem is a kind of typical production scheduling problems. The majority of this kind of problem is NP-hard computational complexity. Local search are easily trapped into local optima. This paper decomposes No-wait job shop scheduling problem into two sub-problems. Then proposed an inverse problem based algorithm for the first sub-problems. and a K-neighborhood search...
A novel approach is introduced in this paper to develop an integrated antenna switch module (ASM) for DCS/UMTS user equipment applications. The realizations of this module are mainly based on the 3-D integrations of using the LTCC (low-temperature co-fired ceramic) substrate and PIN diode, through which PA and LNA can be connected with the antenna directly. Measurement results show its in-band isolation...
Due to the nonlinearity of the switching process in DC-DC converters, the stability analysis with traditional linear modelling for DC-DC converters are invalid sometimes, especially in the transition interval from stable region to unstable region. In this paper, describing function method is firstly adopted in switching process modelling of DC-DC converters. Further, a new model based on describing...
A realistic 2GHz human in-head near-field path-loss (NF-PL) modeling approach is presented in this paper. Due to the facts that the EM near-field interactions and in-head NF-PL characteristic are fully reflected in the simulation system, which consists of a verified UWB antenna and a well-known head-phantom, the NF-PL parameters can then be extracted in terms of this rigorous simulated results. The...
Short-term load forecasting refers to daily and weekly load forecasting, which plays a vital role in ensuring security and high quality of power system's economic operation for power generation planning. In short-term load forecasting, load periodicity with the fixed regularity is generally analyzed and random factors like weather are taken into consideration to improve the accuracy of the forecast,...
A 27nm 16Gb Cu based NV Re-RAM chip has been demonstrated. Novel process introduction to enable this technology include a Damascene Cell, Line-SAC Digit Lines filled with Cu, exhumed-silicided array contacts, raised epitaxial arrays, and high-drive buried access devices.
Without the applicable methods of forecasting the outbreak of debris flows in a wide area as well as long time, wireless sensor networks (WSN) of monitoring debris flow are essential for protecting safety and property of human. In nowadays, a common and key consideration of the network would be the energy efficiency, since both of the soil moisture (SM) sensor and the radio are power-hungry, meanwhile,...
GPS L2C signal is one of the modernized GPS civilian signals. With respect to GPS L1 C/A signal, L2C signal is more robust in harsh environment, since its tracking threshold would be lower by taking the advantage of new designed pilot channel. Up to now, some of current tracking methods are only based on the pilot channel or data channel of L2C signal and discard the other, which results in 50% power...
A dual-polarized impulse radiation antenna (DP-IRA), with low profile and high gain, is presented in this paper for cerebral hemorrhage detection.

Simulation data shows that the antenna can detect cerebral hemorrhage as well as diagnose bleeding situation in a direct...
With the rapid development of the intelligent mobile terminal equipment, all kinds of English word mobile learning software have been appeared on the market. These learning software make way to memorize English words more diversified and efficient. However, many words in the thesaurus software are simply presented to the learner, but do not reflect the memory management function modules. In addition,...
In this study, a chaotic analysis approach was applied to a time series composed of seismic moment of events occurred in mine of Dong Gaussian copper mine subordinate to Tong Ling Nonferrous Metals Group Co. In Anhui province, China. The chaotic attractor dimension and the largest lyapunov index were put forward to determine whether the seismic flow of rock is chaotic and the degree of chaos. The...
